Unembedding Steering Benchmark

Hugh van Deventer, Itamar Pres, Liam Cawley

2024

A benchmark for evaluating steering methods that operate through a language model's unembedding matrix. Provides standardized comparisons across extraction methods, models, and tasks.

nanoSandbox

Liam Cawley

2024

A minimal distributed training sandbox for nanoGPT. Experiments with MIG partitioning, NCCL collectives, Kubernetes orchestration, and mixed-precision training on small-scale hardware.

DDPM-Inspired Single Image Super Resolution

Liam Cawley, Alexandra Lavacek, Sophia Tesic

Course project, University of Michigan|2024

Adapting denoising diffusion concepts to single-image super resolution. We progressively build from a naive upsampler to a residual architecture with channel attention and perceptual loss, achieving 34.0 dB PSNR on DIV2K at 2x upscaling.

Context Manipulation Attack Benchmark

Liam Cawley

2023

An undergraduate benchmark for conversation-history poisoning attacks on language models, covering false conversation injection, gaslighting, and iterative context poisoning. Added in retrospect with notes on what the setup does and does not establish.

Phased Array Calibration via Metaheuristic and Learned Optimizers

Liam Cawley, Gabe Ronan

EMAG Technologies, Inc.|2023

A closed-loop calibration application for an active electronically scanned phased-array radar, optimizing 6-bit phase-shifter and attenuator states on Anokiwave AWS-0103 beamformers with metaheuristic search and a CNN surrogate, reaching a 6.5x reduction in beam-synthesis error over a Sample Matrix Inversion baseline.

Shake-Shake Regularization in ResNet Architectures

Liam Cawley

Course project, University of Michigan (Qing Qu)|2023

An empirical comparison of stochastic regularization methods --- Shake-Shake, Mixup, and Cutout --- in residual networks on CIFAR-10, with analysis of when and why each technique helps.

Autonomous Fixed-Wing UAV

Liam Cawley

2021

Design of a fully autonomous fixed-wing UAV on the MFD Crosswind platform for agricultural seed spreading and mapping, benchmarked against the AUVSI SUAS 2021 mission of waypoint navigation, object detection, and a parachute UGV airdrop.
